To all whmn it may concern.-

Be it known that I, J OI-IANN HEINRICH SroERL, a subject of theEmperorof Germany, residing in Dusseldorf, Empire of Germany, haveinvented certain new and useful Improvements in Apparatus for Folding,Piling, and Cutting Paper and the Like, of which the following is aspecification.

This invention relates toand has for an object to provide improvedapparatus for alternately folding in opposite directions on perforatedlines at uniform distances apart a web delivered from rotaryprinting-presses, the said web being, if desired, separated into pilescontaining a certain number of sheets, so that removal thereof can beeffected without stopping the machine.

One form of the apparatus is illustrated in the drawings accompanyingand forming a part of this specification, wherein Figure 1 shows across-section of the mechanism and shows the position of therightgripper 0 on the upper sheet, which has been stripped from the rightcylinder and is folded in zigzag form on the line of transverseperforations. Fig. 2 is a similar view to Fig. 1, with the differencethat the movable parts are in a different. position; otherwise thisfigure shows the moment of the cutting off after piling a predeterminednumber of sheets; and Fig. 3 shows the cylinders b 6 looking from thetop.

The web a, transversely perforated at uniform intervals, is conducted tothe cylinders 6 and 6 in the present instance from the top, half thecircumference of each of which is equal to the distance between twolines of perforations in the web. Each of these cylinders b b isprovided with a row of thin and pointed pins 71: 70, which respectivelyenter the guideway m and the recess 70 and penetrate the web close tothe perforated lines, so that the sheet is alternately moved to theright and left by the cylinders and folded at the perforated lines. Thecylinders are mounted on shafts 6 b and adjacent to the cylinders arearranged grippers c 0', which are fast upon rock-shafts (Z (Z In thepresent instance there are shown several grippers for to its properplace.

each cylinder. Upon the rock-shafts are also 'fast segments (Z cl.

As seen in Fig. 1, the shaft (Z has fast upon it an arm cl, which ispivoted to pitman 5*, having an eye connected to a crank If, whereby thegripper 0 and the segment (Z are oscillated. The shaft d also has an armd, which is connected, by means of a link (Z with an arm (Z upon therock-shaft (Z whereby the motion transmitted from the cam 7f willactuate the grippers in unison, which in their uppermost positionsextend into recesses g g, in the cylinders in order to remove the paperfrom the pins 7:; 70 at the rightmoment and to press it down upon thetable 7 Below these grippers are plate-shaped countergrippers ff, whichlatter grippers are fast upon the shafts of pinions e e, meshing withthe segments d d, and upon the upward movement of the gripper 0 thegripper f will doscend, and upon the downward movement of the gripper 0the gripper f will be thrown completely out of the path of movement ofthe gripper c, as will be clearly seen in Fig. 2. By this means when thegripper f comes down upon the paper to force it in place and pile it thegripper f at the other side will engage the paper and prevent the pilefrom being disturbed by the action of the former gripper. This action ofthe grippers continuously justifies the pile by forcing each fold Thegrippers ff" also serve to press the pile of paper at the fold and pressit entirely flat.

, The machine may also be provided with a device for cutting the webwhen a certain number of sheets have been folded without stopping themachine. In a guideway m in one of the cylinders-for instance, bisarranged a movable knife m, guided by pins or rods Z and adapted toenter a groove 0 in the other of said cylinders to cut the web. Theguide pins or rods Zcarry abutments 76, which may be engaged by strikersq, carried by a shaft (1 Such shaft g will be driven by a gear-wheel a,fast upon itfand in mesh with a gear-wheel a, fast with the shaft 6 Thegear-wheel n will be provided with as many teeth as it is desired to laydouble sheets upon the table z', and the gear-wheel n will be providedwith one less than such number of teeth, whereby after the cylinder 1)has revolved the predetermined number of times the strikers q willregister with the abutments k and advance the knife against the pressureof the spring m, which after the further rotation of the gear wheelsforces the knife back into its idle position and there holds it untilthe knife is again pressed forward.

Having thus described my invention, I claim 1. The combination with apair of rotatable rolls adapted to seize a web of paper and draw thesame between them, a row of pins upon each cylinder the row of one beingdodged relatively to the row of the other whereby a portion of the papermay be carried partially around the periphery of one and then anotherportion partially around the periphery of the other roll, means forstripping the paper from the rolls and laying the same in a pile, andmeans for pressing the pile of paper at the folds after it has been solaid.

2. The combination of a pair of rolls adapted to draw aweb of paperbetween them, means to rotate the rolls, pins upon the peripheries ofthe rolls adapted to engage paper passing between the same, means tostrip the paper from the rolls and pile the same, means to press thefolds, and means to cut the web after a predetermined number of folds.

3. The combination with a pair of cylinders each having upon one side arow of pins to engage a web of paper passing between the rolls and uponits other sidea row of recesses to accommodate the pins of the otherroll, means to remove the paper from the rolls, and means to justify thepile and press the folds.

4. In a machine of the character described the combination with means tofeed paper toward a table, means to alternately fold the same inopposite directions, means to lay at each side of the pile thelast-formed fold upon the pile, and means at each side of the pile toact in conjunction therewith to press the paper and hold the same frommovement during the action of the laying-on device.

5. The combination with a pair of cylinders adapted to seize and drawbetween them a web of paper, means to fold the paper alternately inopposite directions, a knife carried by one roll and mounted therein forradial reciprocation, a striker mounted upon the shaft and adapted toforce the knife forward, and a train of gear-Wheels carried by the saidshaft and the roll carrying the knife, the gear-wheel upon the rollhaving a number of teeth equal to the number of sheets it is desired topile, and the wheel upon said shaft having one less number of teeth.

6. The combination with a pair of rotatable cylinders adapted to seize aweb of paper and draw the same between them and provided with recessesto receive pins carried by the other cylinder, a row of pins upon eachcylinder to enter said recesses, the pins adapted upon the rotation ofthe cylinders to engage the paper and carry the same in foldsalternately toward the respective slides of a table, a table whereonsuch paper may be piled, a number of recesses in each cylinder, armsadapted to enter such recesses and upon movement of the same toward thetable to strip the paper from the pins, means controlled by the rotationof the cylinders to alternately actuate said strippers, means controlledby said respective strippers to engage the opposite side of the pileduring the action thereof, and an automatic cutting-off device.
